Iscar 5508404 Replaceable Drill Tip 0.512 in Carbide

Product Description

The ISCAR 5508404 is a replaceable drill tip designed for high-performance drilling in demanding materials including stainless steel, superalloys, and titanium. Built from solid carbide in the ICM series, this tip carries a TiAlN coating applied via PVD process and is manufactured to the IC908 grade with a submicron material grade for edge integrity under thermal and mechanical stress. The 140-degree drill point angle and web-thinned point geometry reduce entry force and improve centering on difficult workpieces. With a cutting diameter of 0.512 inches and a functional length of 0.220 inches, the 5508404 is a compact, precision-ground tip suited for production drilling environments.

This tip is used in drilling applications across aerospace, medical, and general machining where stainless steel, titanium, and nickel-based superalloys are common workpiece materials. It also handles secondary applications in steel, cast iron, and hard materials. The T-Land style insert geometry and slow spiral flute type are matched to the cutting demands of ISO material groups M, S, P, K, and H. It fits insert seat size 13 and is held by twist-style seating, making it compatible with ISCAR ICM 130 exchangeable-head drill bodies. Installation requires no coolant-through configuration.

Key Features

• Solid carbide construction with submicron material grade for consistent edge retention
• TiAlN PVD coating for heat resistance in stainless steel, superalloy, and titanium drilling
• 140-degree included angle with web-thinned point for reduced thrust force and accurate entry
• T-Land insert geometry with slow spiral flutes optimized for ISO M and S workpiece materials
• Twist-style seating into insert seat size 13 for secure, repeatable tip indexing
• Conforms to ISO 13399 tooling data standards

Compatibility

Designed for use with ISCAR ICM 130 exchangeable-head drill bodies using insert seat size 13 and twist-style tip retention. Compatible with ISO material groups M, S, P, K, and H.

Installation Notes

Replaceable drill tips of this type are installed and serviced by machinists or tool-room technicians. Ensure the drill body and seating surface are clean and free of chips before installing the tip. Use the recommended ISCAR torque tool or driver to seat the tip securely by twist engagement. Do not overtighten or use impact tools, as this can damage the carbide seating interface or the tip itself.
